I'm a newbie here, although I have lurked a bit and tried some of the suggested fixes for my recent problems. Sorry if this is a long post but I try to give a full description.
DELL Vostro 1500 laptop with Vista Business SP2 + all updates; bought Nov 2007 with Vista installed. It has not been re-installed.
Avast free AV running in real time (Windows Defender turned off).
Malwarebytes Anti-Malware free version installed, kept up to date and used for weekly scans - not running in real time
Browser: Firefox 3.6.14
The computer is regularly checked and cleaned using CCleaner
I have been running Soluto Beta (Soluto) since last June (without any problem as far as I know).
In the last few days (I think it started Monday 28 Feb) my Vista system has started giving me BSOD events 2 or 3 times per day. The system freezes, I get the BSOD but not really enough time to read carefully what the info says.
Action taken so far:
* ChkDsk - no problems reported
* Memory check - no problems reported (twice)
* The C:\ drive had about 10% free space. I've cleared some old files, compressed some photos, generally cleaned up. Now it has 61GB free out of 136GB - and the BSOD still occurs.
* Swapped my Advent wireless mouse for a wired USB mouse (see below)
* Used CCleaner to clean up the Registry and release disk space
* Done a defrag using MyDefrag (MyDefrag v4.3.1)
The problem persists.
I am suspicious about:
* new stuff:
(this is my prime suspect)
A couple of weeks ago I bought a USB-to-parallel adaptor cable so I could use my (trusty) old HP Laserjet5L printer from my laptop. This all worked fine from the moment I plugged it in, but after a day or two started to cause problems - not printing; couldn't find the printer; wanted to keep installing drivers, etc. This occurred more or less at the same time as the BSOD problems. However, I have disconnected the cable and removed the printer from the printer list - still get the problems. Nevertheless maybe there is a faulty driver acquired from goodness knows where. I do not know how to find and delete such a driver. It doesn't show up in any of the obvious places and I don't know where to look for it in Device Manager.
Other new stuff:
I bought a new wireless modem/router (Belkin F5D8636uk4A) about 2 weeks ago. I'm only suspicious because it's new - no other reason. My partner's laptop (identical to mine) is working fine.
The mouse: it seems to me that the BSOD always happens at an instant when I am moving the mouse. Maybe. Although I have had the Advent wireless mouse for a couple of years, I stopped using it (but kept using the keyboard) about a year ago. I recently found it again and have been trying it again for the last fortnight. However, as I said above, now I am using the previous wired mouse, and the BSOD keeps on coming.
I think that's about it. I attach a zip file containing the folder"Windows_NT6_BSOD_jcgriff2" and the PerfMon report, as advised, plus a screenshot of the Windows security centre window, because the PerfMon report claims Windows can't see my Avast AV software. The security centre can see it. Although auto-update is not turned on, I always install updates within a day or so (usually within an hour or so) of notification. (I just don't like the darned thing doing it while I'm waiting for the system to boot up).
Any help/advice most gratefully received! Thanks,
